COOKING-STOVE.

Specification of Letters Patent No. 340, dated July 31, 1837.

To all evhom it may concern:

Be 1t known that I, JOHN COLL-UM, of

Grafton, in the county of Worcester and Commonwealth of Massachusetts,tin-plate worker, have invented a new and useful Improvement in theCooking Stove and Baker,

The body of the baker or stove consists of an oblong box of tin plate orother metal, set on metal legs of convenient height. The ends are to bemade parallel with each other and are provided with doors opening intothe interior of the body or oven. The sides are also parallel with eachother and the corners are square, the top rises several inches above thebody of the stove orbaker, and has four sides sloping toward the middle,where a square surface is left with an opening to receive the boilingapparatus. The bottom is sunk several inches below the body of the stoveor baker, having, like the top, four sides sloping toward the middle,where another square fiat surface,with an opening is formed forreceiving a furnace. The top and bottom are in the shape of a truncatedpyramid, the former rising above and the latter sinking below the bodyof the stove or baker.

On the flat surface of the middle of the bottom, is set a small furnacefor burning coal or other fuel, with a proper grate. Below this grate isan opening in the bottom of the stove for the admission of air, and topermit ashes and cinders to fall. A plate of metal, sliding on groovesor ledges, is so fixed as to close the opening either partially orentirely, serving as a damper to regulate the draft. Under this damper,a drawer is placed, to receive ashes and cinders from the furnace,having the front and back ends so much lower than the sides as to admitof the passage of air to the furnace above. A cover of sheet iron isplaced over the furnace, fitted with a pipe or funnel to convey the heatand smoke generated by the furnace. This pipe is carried through themiddle till it reaches above the body of the oven or baker. On the topof the pipe is set a round or oval receiver, shaped like a tunnel at thelower end where it joins to the pipe, swelling out above large enough toreceive one or more kettles or boilers to be heated, and rising a fewinches above the flat surface of the top of the stoves. The cover of itsuse.

the receiver is made of iron having suitable apertures to receive oneor'more kettles or boilers. Under it is a smoke pipe like that in commonuse to carry away the smoke coming from the furnace. A

, On the inside of the oven of the stove or baker, and on the level ofthe opening of the doors, a bar is placed longitudinally on each side.Shelves are made to slide on the bars for supporting loaves of bread orother articles to be baked or roasted, or dishes. Above these shelves,at suitable distances, other bars are fastened to the sides to supportround or flat bars instead of shelves. These admit of being removed withconvenience when large articles are deposited on the shelves under.

WVhen the apparatus is to be used, on removing the kettles or boilersfrom the top of the stove, wood, coal, or other fuel may be pouredthrough the openings of the top of the receivers into the furnace, andthe fire kindled. The heat, ascending through the pipe over the furnace,is radiated through the body or oven of the stove, and on entering thereceiver is diffused around the kettles or boilers. sides of the top andbottom, the heat is reflected, reverberated, and concentrated on theoven of the baker or stove. The result of this construction is greateconomy in the consumption of fuel, and great expedition in the processof cooking.

The stove or baker may be constructed of tinplate, sheet iron, copper,or other metal. The inside should be kept bright so as better to reflectthe heat from the several surfaces. The size may be such as will bestsuit the convenience of thefamily requiring The stove may be "ery lightand portable and fitted withhandles so as to be easily removed fromplace to place.

That which I claim as my invention and desire to secure by LettersPatent is- The manner in which heat is communicated to and diffusedthrough the oven of the stove or baker in the manner before described. V
